The floral morphology of four Chinese Bambusa species (Poaceae, Bambusoideae) previously described only from vegetative material

Abstract

Due to their specialised flowering biology where frequent or even annual flowering is uncommon, reproductive materials of bamboos are not always available, so hampering taxonomic interpretation and research into other aspects. Bambusa contracta, B. corniculata, B. cornigera and B. subtruncata were established only based on vegetative materials and flowering or fruiting material has been hitherto unknown. The floral morphology of these four species is described for the first time and, correspondingly, epitypes are designated to support a more complete interpretation of the species
